我国探望权主体扩大化的法律思考

我国现有法律对探望权主体规定过于狭窄,本文认为父母、祖父母、外祖父母、兄弟姐妹及子女在较长时间内受其家庭养育的人都可以成为探望权的主体;应当从保护子女利益的前提下,对探望权主体的权利行使进行适当限制;未成年子女不能作为探望权的主体.     

再谈城市规模效益问题

我国目前正处于大城市化阶段, 城市规模效益规律仍是贯穿于城市发展过程中的重要客观规律。对于这一规律, 本文从社会成本与收益对比的角度, 通过实证分析加以验证。笔者认为, 在发展社会生产力为主要任务的今天, 城市规模效益应当成为制定城市发展政策的主要依据。对于城市化过程中出现“城市病”问题, 可以通过一定的途径加以缓解和避免。     

Do Spin‐offs Expropriate Wealth from Bondholders?

A wealth transfer from bondholders to stockholders is one of several hypotheses used to explain stockholder gains on the announcement of a spin‐off. However, previous empirical research has not found systematic evidence supporting the wealth expropriation hypothesis. Using a larger sample with comprehensive bond data, we find evidence consistent with wealth expropriation. Bondholders, on average, suffer a significant negative abnormal return during the month of the spin‐off announcement. However, even accounting for the loss to the bondholders, the aggregate value of the publicly traded debt and equity increases on a spin‐off announcement, suggesting that the wealth expropriation hypothesis is not a complete explanation of the stockholder gains. In explaining the magnitude of the losses to bondholders, we find they are a function of the loss in collateral in the spun‐off subsidiary and the level of financial risk of the parent firm. Consistent with a loss to bondholders, firms are more likely to have their credit rating downgraded than upgraded after a spin‐off. Additionally, consistent with the wealth transfer hypothesis, losses to bondholders tend to be more severe, the larger the gains to shareholders.

INFORMED TRADING RISK AND BID-ASK SPREAD CHANGES AROUND OPEN MARKET STOCK REPURCHASES IN THE NASDAQ MARKET

Microstructure theory contends that dealers' bid-ask spreads should vary intertemporally with changes in the asymmetric information component of the spread. Corporate theory suggests that stock repurchase announcements signal management's private information to the securities markets. An examination of dealers' spread behavior around firms' open market repurchases in the NASDAQ market reveals a decline in spreads adjusted for dealers' inventory-holding and order-processing costs. This decline is attributed to a reduction in informed trading risk associated with the open market repurchase announcements.     

Inflation-induced adaptive behavior

Periods of rapidly rising prices are seen by many as cyclical and pervasive phenomena in modern day economic systems. When rapid price increases occur, they are likely to induce adaptive behavior on the part of consumers. This article reports on a study seeking to analyze consumer inflation-induced adaptive behavior as it relates to three food-related consumer activities–food buying, preparation, and consumption. Results indicate that consumers, in general, attempt to adjust to the changing economic environment in several ways: they exercise more care and planning in food shopping, are more price sensitive and price conscious, are willing to sacrifice convenience but not quality, and try to maintain their usual level of food consumption and food habits. Results also indicate that inflation leads to greater adaptive behavior on the part of lower income consumers.     

Remarks on the strong law of large numbers for a triangular array of associated random variables

A strong law of large numbers for a triangular array of strictly stationary associated random variables is proved. It is used to derive the pointwise strong consistency of kernel type density estimator of the one-dimensional marginal density function of a strictly stationary sequence of associated random variables, and to obtain an improved version of a result by Van Ryzin (1969) on the strong consistency of density estimator for a sequence of independent and identically distributed random variables.

保额及费率的异常变化对财产保险经营的影响

近年来，随着市场竞争态势的加剧，我国财产保险市场保额和费率呈现异常变动态势，再保险公司的稳健经营、保险市场的竞争秩序、政府的监督管理及消费者利益的维护带来一系列负面影响。为改变这种状况，从宏观上政府监管机构应强化监管，行业协会应发挥好引导、协调、监督作用。大力加强全社会诚信体系建设；从微观层面上保险公司应加强内控管理、强化风险意识、削减经营成本、培育创新能力，建立一套完整的费率实施和管理体系。
